Claude usage at $20 is basically unusable for serious work. I haven't used Kimi but I'd have to imagine they're offering a good deal more usage for the same price.

They tick all the boxes I care about – desktop & mobile app, cli – but for the same price I might as well just go for the leading providers.

for similar plan i think claude costs like $100 a month?

Because Opus on $20 CC is a joke. The $19 plan on Kimi has actually workable usage limits.
